'''''Halo 2''''' is a 2004 [[First person shooter game|first-person shooter]] [[video game]] developed by [[Bungie]] and published by [[Microsoft Game Studios]] for the [[Xbox (console)|Xbox]] console. ''Halo 2'' is the second installment in the [[Halo (franchise)|''Halo'' franchise]] and the sequel to 2001's critically acclaimed ''[[Halo: Combat Evolved]]''. The game features new weapons, enemies, and vehicles, another player character, and shipped with online multiplayer via Microsoft's [[Xbox Live]] service. In ''Halo 2''{{'}}s story mode, the player assumes the roles of the human [[Master Chief (Halo)|Master Chief]] and alien [[Arbiter (Halo)|Arbiter]] in a 26th-century conflict between the [[United Nations Space Command]], the genocidal [[Covenant (Halo)|Covenant]], and later, the parasitic [[Flood (Halo)|Flood]].
'''''Halo 2''''' is the [[sequel]] to the blockbuster and critically-acclaimed ''[[Halo: Combat Evolved]]'', and features a newly built [[game engine]] and the [http://bungie.net/News/TopStory.aspx?story=havokhalo2feature Havok] [[physics engine]], new weapons and vehicles, new multiplayer maps, and a storyline that continues the story begun in Halo: Combat Evolved. ''Halo 2'', released for the [[Xbox]] [[game console]] on [[November 9]], [[2004]], and its predecessor are both backwards-compatible for the [[Xbox 360]], including its [[Xbox Live]] functionality.
 
After the success of ''Halo: Combat Evolved'', a sequel was expected and highly anticipated. Bungie found inspiration in plot points and gameplay elements that had been left out of their first game, including online multiplayer. A troubled development and time constraints forced cuts to the scope of the game, including the wholesale removal of a more ambitious multiplayer mode, and necessitated a [[cliffhanger]] ending to the game's campaign mode. Among ''Halo 2''{{'}}s marketing was an early [[alternate reality game]] called "[[I Love Bees]]" that involved players solving real-world puzzles. Bungie supported the game after release with new multiplayer maps and updates to address cheating and glitches. The game was followed by a sequel, ''[[Halo 3]]'', in September 2007.
==History==
This game sucks.
 
''Halo 2'' was a commercial and critical success and is often listed as one of the [[List of video games considered the best|greatest video games of all time]]. The game became the most popular title on Xbox Live, holding that rank until the release of ''[[Gears of War (video game)|Gears of War]]'' for the [[Xbox 360]] nearly two years later. ''Halo 2'' is the best-selling first-generation Xbox game, with more than 8 million copies sold worldwide. The game received critical acclaim, with the multiplayer lauded; in comparison, the campaign and its cliffhanger ending was divisive. The game's online component was highly influential and cemented many features as standard in future games and online services, including matchmaking, lobbies, and [[Clan (video games)|clans]]. ''Halo 2''{{'}}s marketing heralded the beginnings of video games as [[blockbuster (entertainment)|blockbuster]] media. A port of the game for [[Windows Vista]] was released in 2007, followed by a high-definition remake as part of ''[[Halo: The Master Chief Collection]]'' in 2014.
==Gameplay==
campaign sucks.

[[File:Halo 2 (screenshot).jpg|thumb|left|In-game screenshot of ''Halo 2'' for Xbox; the player character aims a shotgun at enemy Covenant.]]
{{main|List of multiplayer gametypes in Halo 2}}
''Halo 2'' is a [[shooter game]]. Players primarily experience gameplay from a [[First-person shooter|first-person]] perspective, with the viewpoint shifting to third-person for vehicle segments.<ref name="gamespot-review" /> Players use a combination of human and Covenant weaponry and vehicles to progress through the game's levels. Certain weapons can be [[dual wield|dual-wielded]], allowing the player to trade accuracy, the use of [[hand grenade|grenades]], and melee attacks for raw firepower.<ref name=manual /> The player can carry two weapons at a time (or three if dual-wielding, with one weapon remaining holstered), with each weapon having strengths in different combat situations. Most Covenant weapons, for example, eschew disposable ammo magazines for a contained battery, which cannot be replaced once depleted. However, these weapons overheat if fired continuously.<ref name=manual /> Human weapons are less effective at penetrating shields and require reloading ammunition, but cannot overheat due to prolonged fire. Players can [[Boarding (attack)|hijack]] enemy vehicles and quickly assume control of them. The player is equipped with a damage-absorbing shield that regenerates when not taking fire; their [[life bar|health bar]] is not visible.<ref name="manual">{{Cite book |title=Halo 2 Instruction Manual |publisher=[[Microsoft Game Studios]] |year=2004 |editor-last=Bungie}}</ref>
[[Image:Halo2 multi 4 1094806526.jpg|thumb|right|[[Xbox Live]] automatically matches players based on criteria such as skill and [[ping]].]]
[[Image:Halo2 multi 2 1094806396.jpg|thumb|right|''Halo 2'' multiplayer screenshot from press kit, featuring the map Zanzibar]]
There are varying modes, several of which have returned from the original ''Halo'' game. A typical classic free for all or team deathmatch game known as Slayer, a team based Capture The Flag game, a game which you plant a bomb in your enemies base to score called Assault, a more esoteric free-for-all (FFA) or team game of keep away called Oddball, a game extrapolated from a child's game of "tag" called Juggernaut, King of the Hill, where players race to control a specified area of the map, and finally, Territories, which bears some resemblance to King of the Hill, but with multiple hills. All of these modes can be twisted and changed in thousands of unpredictable ways, resulting in incredibly varied multiplayer gameplay. Of the preset variations present in the original game, only Race is missing.
 
The game's "Campaign" mode offers options for both [[single-player]] and cooperative [[multiplayer video game|multiplayer]] participation. In campaign mode, the player must complete a series of [[level (computer and video games)|levels]] that encompass ''Halo 2''<nowiki>'</nowiki>s storyline. These levels alternate between the [[Master Chief (Halo)|Master Chief]] and a [[The Covenant (Halo)|Covenant]] Elite called [[Arbiter (Halo)|the Arbiter]], who occupy diametrically opposed roles in the story's conflict. Aside from variations in storyline, the Arbiter differs from Master Chief only in that his armor lacks a flashlight; instead, it is equipped with a short duration rechargeable form of [[active camouflage]] that disappears when the player attacks or takes damage.<ref name="xbox-thebigone">{{Cite web |last=McLain, Alex |year=2007 |title=The Big One |url=http://www.xbox.com/en-US/games/h/halo2/spotlight14.htm |url-status=dead |archive-url=https://web.archive.org/web/20070706132208/http://www.xbox.com/en-US/games/h/halo2/spotlight14.htm |archive-date=July 6, 2007 |access-date=October 20, 2007 |website=Xbox.com |publisher=Microsoft Corporation}}</ref> There are four [[difficulty level]]s in campaign mode: Easy, Normal, Heroic, and Legendary. An increase in difficulty will result in an increase in the number, rank, health, damage, and accuracy of enemies; a reduction of duration and an increase in recharge time for the Arbiter's active camouflage; a decrease in the player's health and shields; and occasional changes in dialogue. Enemy and friendly artificial intelligence is dynamic, and replaying the same encounters repeatedly will demonstrate different behavior.<ref name="gamespot-review" />
Unlike its predecessor, ''Halo 2'' allows players to compete with each other via the [[Xbox Live]] online service, in addition to the original's support for split-screen and System Link multiplayer. ''Halo 2''<nowiki>'</nowiki>s Xbox Live mode offers a unique and, some would say, innovative approach to online gaming that is intended to alleviate some of the problems that have plagued online first-person shooters in the past. Traditionally, one player sets his or her computer or console up as a game [[server]] (or [[host]]), specifying the game type and [[Level (computer and video games)|map]] and configuring other settings. The game software then uses a service like Xbox Live or [[GameSpy]] to advertise the game to the world at large; other players choose which game to join based upon criteria such as the map and game options each host is offering as well as the [[ping]] times they are able to receive.
 
=== Multiplayer ===
In ''Halo 2'', Xbox Live players do not choose to host public games, and they do not get to specify individual maps and options to search for. Instead, players select "playlists" that are geared to different ''styles'' of play. For example, the "Rumble Pit" playlist offers a variety of "every man for himself" game types, primarily Slayer or variations thereof; "Team Skirmish" offers a number of 4-on-4 team games, which are primarily objective-based games like [[Capture the Flag]]; "Big Team Battle" is similar to Team Skirmish but allows teams of up to 8 players. Other playlists allow head-to-head play and matches between different [[Clan (computer gaming)|clans]]. The Xbox Live servers create games automatically from the pool of players that have chosen each playlist, choosing a game type and map automatically and selecting one player to serve as the game's host.
Like ''Halo: Combat Evolved'', the Xbox version of ''Halo 2'' features a multiplayer system that allows players to compete with each other in split-screen and system link modes; in addition, it added support for [[Multiplayer online game|online multiplayer]] via [[Xbox Live]].<ref name=manual /> The Xbox Live multiplayer and [[downloadable content]] features of the Xbox version of ''Halo 2'' were supported until the discontinuation of the service in April 2010,<ref>{{Cite web |last=Whitten, Marc |date=February 5, 2010 |title=A Letter from Marc Whitten: Discontinuation of Xbox LIVE for Original Xbox Games |url=http://www.xbox.com/en-US/Press/Archive/2010/0205-whittenletter |url-status=dead |archive-url=https://web.archive.org/web/20101115041606/http://www.xbox.com/en-US/Press/archive/2010/0205-whittenletter |archive-date=November 15, 2010 |access-date=April 16, 2010 |website=Xbox.com |publisher=[[Microsoft]]}}</ref> with the final multiplayer session concluding May 10, almost a month after the service was officially terminated.<ref>{{Cite web |last=Good |first=Owen |title=The Last Man to Play Halo 2 on Xbox Live |url=https://kotaku.com/5535672/the-last-man-to-play-halo-2-on-xbox-live |url-status=dead |archive-url=https://web.archive.org/web/20110811213757/http://kotaku.com/5535672/the-last-man-to-play-halo-2-on-xbox-live |archive-date=August 11, 2011 |website=[[Kotaku]]}}</ref> In spite of the shutdown, Halo 2 is playable online again on the revival online servers for the original Xbox called [[Insignia (Xbox)|Insignia]].<ref>{{Cite web |author1=Kaan Serin |date=2024-03-15 |title=14 years after Microsoft shut it down, Halo 2 gets new public servers thanks to an unofficial OG Xbox Live replacement |url=https://www.gamesradar.com/14-years-after-microsoft-shut-it-down-halo-2-gets-new-public-servers-thanks-to-an-unofficial-og-xbox-live-replacement/ |access-date=2025-06-15 |website=GamesRadar+ |language=en}}</ref><ref>{{Cite web |date=2024-03-15 |title=Halo 2 Multiplayer Is So Back |url=https://tech.yahoo.com/gaming/articles/halo-2-multiplayer-back-190112528.html |access-date=2025-06-15 |website=Yahoo Tech |language=en-US}}</ref> Multiplayer for the PC version of the game used [[Games for Windows – Live]].<ref name="eurogamer-halo returns to PC">{{Cite web |last=Yin-Poole |first=Wesley |date=December 4, 2019 |title=12 years after Halo 2 Vista, Halo is back on PC – with a bang |url=https://www.eurogamer.net/articles/2019-12-04-12-years-after-halo-2-vista-halo-is-back-on-pc-with-a-bang |website=[[Eurogamer]] |publisher=Gamer Network |access-date=April 11, 2021 |archive-date=April 11, 2021 |archive-url=https://web.archive.org/web/20210411160835/https://www.eurogamer.net/articles/2019-12-04-12-years-after-halo-2-vista-halo-is-back-on-pc-with-a-bang |url-status=live }}</ref> PC multiplayer servers were taken offline in June 2013.<ref>{{Cite web |last=McElroy, Griffin |date=January 17, 2013 |title=Halo 2 PC servers shutting down on Feb. 15 |url=http://www.polygon.com/2013/1/17/3887486/halo-2-pc-servers-shutting-down-on-feb-15 |url-status=dead |archive-url=https://web.archive.org/web/20130120104320/http://www.polygon.com/2013/1/17/3887486/halo-2-pc-servers-shutting-down-on-feb-15 |archive-date=January 20, 2013 |access-date=January 17, 2013 |website=[[Polygon (website)|Polygon]]}}</ref><ref name="pc support">{{Cite web |last=Tach |first=Dave |date=February 12, 2013 |title=Halo 2 PC multiplayer support extended through June, 343 investigating 'further support options' |url=http://www.polygon.com/2013/2/12/3981338/halo-2-windows-pc-multiplayer-extended-june-343-industries-bungie |url-status=live |archive-url=https://web.archive.org/web/20130215080852/http://www.polygon.com/2013/2/12/3981338/halo-2-windows-pc-multiplayer-extended-june-343-industries-bungie |archive-date=February 15, 2013 |access-date=February 13, 2013 |website=[[Polygon (website)|Polygon]] |publisher=[[Vox Media]]}}</ref>
 
Instead of implementing multiplayer by having players manually join lobbies, as was common in games at the time, ''Halo 2'' used [[Matchmaking (video games)|matchmaking]]. Players chose the general type of match they want to play, and the game selected the map and gametype and automatically found other players.<ref name="polygon-halo 2 ruined">{{Cite web |last=Hopson, John |date=July 2, 2019 |title=The time I tried to ruin Halo 2 |url=https://www.polygon.com/features/2019/7/2/18651880/the-time-i-tried-to-ruin-halo-2-user-research |access-date=January 17, 2020 |website=[[Polygon (website)|Polygon]] |publisher=Vox Media |archive-date=April 23, 2020 |archive-url=https://web.archive.org/web/20200423103902/https://www.polygon.com/features/2019/7/2/18651880/the-time-i-tried-to-ruin-halo-2-user-research |url-status=live }}</ref> This "[[Matchmaking (video games)#Playlists|playlist]]" system automated the process of finding matches to keep a steady flow of games available at all times, and combined a skill-ranking system on top.<ref>{{Cite web |date=January 30, 2007 |title=Halo 2 Matchmaking Overview |url=http://halo.bungie.net/stats/content.aspx?link=h2matchmaking |url-status=dead |archive-url=https://archive.today/20130615225057/http://halo.bungie.net/stats/content.aspx?link=h2matchmaking |archive-date=June 15, 2013 |access-date=April 25, 2012 |publisher=[[Bungie]]}}</ref>
Players can create small "parties" with their friends and enter games together as teammates in Team based games. Parties can also play in "Rumble Training" games, which is an unranked version of "Rumble Pit" If the Xbox console hosting the game drops out, the Xbox Live service automatically selects a new host from among the remaining players so the game can continue. Players may still choose to set up games for their own party to their own specification, and invite others into that game from their Friends and Clan lists, however these games are not made publicly available.
 
== Synopsis ==
Since launching in [[November 2004]], the service has been very popular with video gamers. While some players resent the loss of individual control inherent in ''Halo 2''<nowiki>'</nowiki>s approach to online gaming, others feel it provides a significantly improved gaming experience compared to more traditional online first-person shooters. Bungie's servers match players up by skill level, which tends to eliminate the kind of severely imbalanced games that less-skilled players often consider unfair and unenjoyable. The automatic host selection process also eliminates the ability of the host to exert outsized control over the parameters of the game.
=== Setting ===
{{See also|Halo: Combat Evolved|Factions of Halo}}
''Halo 2'' takes place in the 26th century. Humanity, under the auspices of the [[United Nations Space Command]] or UNSC, have developed [[faster-than-light]] slipspace travel and colonized numerous worlds.<ref name="manual" /> Human worlds come under attack by a collective of alien races known as the [[Factions of Halo#Covenant|Covenant]]. Declaring humanity an affront to their gods, the [[Factions of Halo#Forerunners|Forerunners]], the Covenant begin to obliterate the humans with their superior numbers and technology. After the human planet Reach is destroyed, a single ship, ''The Pillar of Autumn'', follows protocol and initiates a random slipspace jump to lead the Covenant away from Earth. The crew discovers a Forerunner [[ringworld]] called [[Halo Array|Halo]]. Though the Covenant believe Halo's activation will lead to divine salvation, the humans discover that the rings are actually weapons of last resort, built by the Forerunners to contain a terrifying parasite called the [[Flood (Halo)|Flood]]. The human supersoldier Master Chief Petty Officer John-117 and his [[artificial intelligence|AI]] companion [[Cortana (Halo)|Cortana]] learn from Halo's AI monitor, [[343 Guilty Spark]], that activation of the Halos will destroy all sentient life in the galaxy to prevent the Flood's spread. Instead of activating the ring, Master Chief and Cortana detonate the ''Pillar of Autumn''{{'}}s engines, destroying the installation and preventing the escape of the Flood. Master Chief and Cortana race back to Earth to warn of an impending invasion by Covenant forces.<ref>{{Cite book |last=Nylund, Eric |title=Halo: First Strike |title-link=Halo: First Strike |publisher=Del Ray |year=2003 |isbn=0-345-46781-7}}</ref>
 
=== Plot ===
[[Bungie.net]] records every single statistic that is displayed on-screen in the end-of-game "Post Game Carnage Report." Anyone can visit Bungie.net and look at any Xbox Live player's stats. If a player logs in with a [[Microsoft]] Passport, they can also access the "Gameviewer". This presents an image of the level that was played from the player's choice various angles, superimposed with a summary of the crucial game events. For example: for each kill, the attacker and target's locations and the attacker's weapon are displayed, and the paths taken by flags in Capture the Flag games are shown. Bungie keeps these stats for several hundred games per player at a time, then games begin to be purged to save space, and they are used as evidence when banning cheats (see "Xbox Live Updates", below).
''Halo 2'' opens with the trial of a Covenant Elite commander aboard the Covenant's capital city-ship of ''High Charity''. For his failure to stop Halo's destruction, the Elite is stripped of his rank, branded a heretic, and tortured by [[Tartarus (Halo)|Tartarus]], the Chieftain of the Covenant Brutes. Spared execution, the Covenant leadership—the [[Characters of Halo#High Prophets|High Prophets Truth, Regret, and Mercy]]—give the Elite the chance to become an [[Arbiter (Halo)|Arbiter]], a rank given to Elites in times of great crisis or turmoil. As the Arbiter, the Elite quells a rebellion and recovers 343 Guilty Spark.
 
On Earth, Fleet Admiral Hood commends the Master Chief and Sergeant [[Characters of Halo#Avery Johnson|Avery Johnson]] for their [[Halo: Combat Evolved|actions at the first Halo]], with Commander [[Characters of Halo#Miranda Keyes|Miranda Keyes]] accepting a medal on behalf of her deceased father, Captain [[Characters of Halo#Jacob Keyes|Jacob Keyes]]. A Covenant fleet suddenly appears near Earth. In the ensuing battle, a single ship carrying the Prophet of Regret slips through Earth's defenses and besieges the African city of New Mombasa. Master Chief assists in repelling the invasion. With his fleet destroyed, Regret makes a hasty slipspace jump, and Keyes, Johnson, Cortana, and the Master Chief follow aboard the UNSC ship ''In Amber Clad''. The crew discovers another Halo installation; realizing the danger the ring presents, Keyes sends Master Chief to kill Regret while she and Johnson search for the Index, Halo's activation key.
Regular players have expressed concerns regarding the game balance of ''Halo 2''. Many players feel that game strategies are too dependent upon controlling the "power weapons" in each map such as the Rocket Launcher, Sniper Rifle, and Energy Sword, which leads to the overshadowing of the other weapons in the game. Should a team acquire these weapons, it becomes more difficult for their opponents to score kills or attain objectives. Much game time may be consumed attempting to seize the weapons in question from the opposition to shift the balance of power; in some cases it may not even be possible to do so. This primarily affects team games and one-on-one games; in free for alls, a player with a "power weapon" will become a priority target for the other players, meaning that the weapon will change hands frequently. Another common criticism is the dominance of dual-wielding weapons over single-wielding combined with grenades, although attempts have been made to address these issues with the April 18th automatic update (see "[[Halo 2#Xbox Live updates|Xbox Live updates]]").
 
Responding to Regret's distress call, ''High Charity'' and the Covenant fleet arrive at the Halo. After Master Chief kills Regret, the Covenant bombard his ___location; he falls into a lake, where he is dragged away by tentacles. Regret's death triggers discord among the races of the Covenant, as the Prophets give the Brutes the Elites' traditional role as their honor guard. The Arbiter subdues Johnson and Keyes and retrieves the Index. Tartarus appears and reveals that the Prophets have ordered the annihilation of the Elites, and sends the Arbiter falling down a deep chasm.
====Multiplayer maps====
{{main|List of multiplayer maps in Halo 2}}
:''See also: [[Halo 2 Multiplayer Map Pack]]''.
 
The Arbiter meets the Master Chief in the bowels of the Halo, brought together by a Flood creature called the [[Gravemind]]. The Gravemind reveals to the Arbiter that the Great Journey is a lie, and sends the two soldiers to different places to stop Halo's activation. The Master Chief is teleported to ''High Charity'' as the Covenant falls into civil war. The Flood-infested ''In Amber Clad'' crashes into the city, and Cortana realizes that the Gravemind used them as a distraction. As the parasite overruns the city, the Prophet of Mercy is consumed. As for Tartarus, the Prophet of Truth consigns him to Halo with Keyes, Johnson, and Guilty Spark to activate the ring. Master Chief follows Truth aboard a Forerunner ship leaving the city; Cortana remains behind to destroy ''High Charity'' and Halo if Tartarus succeeds in activating the ring.
===Damage system===
[[Image:Shieldhalo2.JPG|thumb|right|The shield's new placement lets the player check damage and motion detector simultaneously.]]
The damage system in ''Halo 2'' is slightly different from that in ''Halo: Combat Evolved''. The player has a regenerating shield, but now has regenerating health as well.
 
On the surface of Halo, the Arbiter joins forces with Johnson and confronts Tartarus in Halo's control room. When the Arbiter tries to convince Tartarus that the Prophets have betrayed them, Tartarus instead activates the ring, and a battle ensues. The Arbiter and Johnson kill Tartarus while Keyes removes the Index; the unexpected deactivation sets Halo and all the other rings on standby for remote activation from a place 343 Guilty Spark calls "the Ark." Meanwhile, Truth's ship arrives at Earth, and Master Chief informs Admiral Hood that he is "finishing this fight."
* '''Shields:''' The [[Deflector shield|shield]] in ''Halo 2'' is much stronger, and recharges at a higher rate. It covers the player's entire body, and slowly decreases in power as it sustains damage. After it takes damage, it starts to recharge 4 seconds after the last time damage was sustained. The power is displayed above the motion tracker in the bottom-left of the screen. Like in the original Halo, once the shields become low an alarm tells you that they are out.
 
In a [[post-credits scene]], Gravemind assumes control of ''High Charity''. Cortana agrees to answer the Flood intelligence's questions.
* '''Health:''' In ''Halo 2'', once the shields run out, the player also has a buffer of health. Unlike the first ''Halo'', health regenerates after the shield. The amount of health left is not visible to the player, and is also much smaller than in the original game.
 
===Powerups= Development ==
There are two types of powerups available in ''Halo 2'' Multiplayer.
 
''Halo'' had never been planned as a trilogy, but the critical and commercial success of ''Combat Evolved''—selling more than five million copies in three years<ref name="theringer-h2 retrospective" />—made a sequel expected.<ref name="eurogamer-better than halo" /> Xbox general manager [[J Allard]] confirmed ''Halo 2'' was in production at [[Electronic Entertainment Expo]] 2002, with a planned release in time for Holiday 2003.<ref>{{Cite magazine |last=Staff |date=July 2002 |title=Halo 2 Confirmed |magazine=[[Official Xbox Magazine|Official Xbox Magazine UK]] |publisher=Future plc |page=20}}</ref>
* '''Overshield:''' An enhanced, non-regenerating shield which is three times the strength of the normal one. The overshield functions on top of the regular shield &ndash; when it is active, the normal shield does not take damage. In addition, when a overshield is picked up, the player is invulnerable until it finishes charging, which takes a second or two. In multiplayer Halo 2, the overshield gradually depletes over time and can be completely taken out with a charged up plasma pistol shot. The overshield is no longer present in the campaign mode of Halo 2. However, the Black Eye Skull will enable the player to charge his/her shield into the overshield range. In certain Multiplayer gametypes, one or more players start with a regenerating overshield.
 
Many at Bungie wanted to make a sequel, building on cut ideas from ''Combat Evolved'' with a more ambitious follow-up.<ref name="vice-untoldhistoryhalo" /> The added publisher support for a sequel allowed greater leeway and the ability to return to more ambitious ideas lost during ''Combat Evolved''{{'}}s development.<ref name="eurogamer-better than halo">{{Cite web |last=Fahey, Rob |date=April 11, 2010 |title=Better Than Halo: The Making of Halo 2 |url=http://www.eurogamer.net/articles/better-than-halo-the-making-of-halo-2-article |url-status=live |archive-url=https://web.archive.org/web/20100411122608/http://www.eurogamer.net/articles/better-than-halo-the-making-of-halo-2-article |archive-date=April 11, 2010 |access-date=April 11, 2010 |website=[[Eurogamer]] |pages=1–7}}</ref> Not satisfied with merely adding back cut content to the sequel, designer Jaime Griesemer recalled that the team "tripled everything," rebuilding the [[game engine]], changing the [[physics engine]], and prototyping a system for stencil [[shadow volume]]s.<ref name="vice-untoldhistoryhalo" /><ref name="art of halo">{{Cite book |last=Trautmann |first=Eric |title=The Art of Halo |publisher=Del Ray Publishing |year=2004 |isbn=0345475860 |___location=New York}}</ref> The game's development would suffer from a lack of clear leadership. Early development discussions happened in small, unconnected teams that did not talk with each other. Bungie cofounder and project lead [[Jason Jones (programmer)|Jason Jones]], who had been exhausted shipping ''Combat Evolved'', similarly burned out during ''Halo 2''{{'}}s production. Jones left the project to work on another Bungie game, ''Phoenix'', leaving fewer people to work on ''Halo 2''. The departure of Bungie's cofounder [[Alex Seropian]] in 2002 caused additional friction and politics in the workplace where Seropian had once mediated tensions. Artist Robert McLees recalled that Bungie had never had good managers, with creatives simultaneously juggling managerial roles. "This kinda worked when there were 12 of us. It worked less well when there were 30 of us. It collapsed when there were 60 of us," he said later.<ref name="rollingstone_2024-11-10"/>
* '''Active Camouflage:''' Drastically reduces the player's visibility for a period of time, making all but a faint outline of him invisible. This effect (which is almost identical to that of the alien armor in the [[Predator]] movies) is reduced if the player is hit by weapons fire, or if he fires a weapon. However, the Energy Sword remains clearly visible even if the player is using camouflage. This feature is included in the Arbiter's armor, though its effect only lasts a few seconds. The powerup is not available in Campaign (the Arbiter can activate it for a short time), and the built-in generator is not available in Multiplayer. The Envy skull gives Master Chief access to the built-in generator.
 
Writer [[Joseph Staten]] described the team's ambitions thusly:<ref name="vice-untoldhistoryhalo" />
'''Gametype Settings:''' In some gametypes, the overshield and/or active camo are always active on one or all of the players, and if disabled, will recharge over time. One common mistake for new players is to mix the overshield and the active camo: this creates a faint halo around the player, caused by the overshield, even though they have active camo.
 
<blockquote>Then we just plowed ahead, much like we'd done with ''Halo'', with one notable exception. We ordered ourselves a giant sandwich, took a bite but didn't realize exactly how big it was before we started in. And we did that across the board, technically, artistically, and story wise. But of course, we didn't figure that out until way too late.</blockquote>

Griesemer put it more bluntly: "What's the phrase? Putting ten pounds of crap into a five-pound bag? We really tried to cram it too full, and we paid the price."<ref name="vice-untoldhistoryhalo" /> Lack of communication led to some team members spending time developing assets or content that was duplicative or wasted. McLees recalled he spent two weeks developing a new weapon that was ultimately cut from the game.<ref name="rollingstone_2024-11-10"/>
===Secrets===
[[Image:Scarab gun halo 2.jpg|thumb|right|The Scarab Gun floats above a red cone high atop a skycraper in the level "Metropolis."]]
The existence of many hidden skulls has been discovered. [http://ducain.org/hihforum/viewtopic.php?t=9] These small objects are hidden in every campaign level in ''Halo 2'', some levels containing more than one. Their effects, while somewhat disputed, can do anything from making the player invisible to removing his HUD. One, called "I Would Have Been Your Daddy," is a maddening skull that, unlike the others, seems to have no reliable mechanism for triggering its appearance. After finding it and picking it up, some players are entered into a battle with more than twenty Elites using only a plasma pistol, with victory leading to new NPC comments[http://nikon.bungie.org/misc/h2dialogue.html?orderby=Category&date=20050707]. However, other users have acquired the skull with no apparent effect at all.
 
An important feature for ''Halo 2'' was multiplayer using Xbox Live. Multiplayer in ''Combat Evolved'' was accomplished via [[System Link]] and had nearly been scrapped altogether in the rush to complete the game.<ref name="theringer-h2 retrospective" /><ref name="vice-untoldhistoryhalo">{{Cite web |last=Haske, Steven |date=May 30, 2017 |title=The Complete, Untold History of Halo |url=https://www.vice.com/en/article/the-complete-untold-history-of-halo-an-oral-history/ |url-status=live |archive-url=https://web.archive.org/web/20180315011247/https://waypoint.vice.com/en_us/article/xwqjg3/the-complete-untold-history-of-halo-an-oral-history |archive-date=March 15, 2018 |access-date=March 27, 2018 |website=[[Vice (magazine)|Vice]] |publisher=Vice Media}}</ref> Most players never played large maps, while a subset greatly enjoyed 16-player action, connecting consoles together with network cables for group play. "We looked at the small set of fans who were able to do this," said engineering lead Chris Butcher, "and just how much they were enjoying themselves, and asked ourselves if we could bring that to everybody. That would be something really special, really unique."<ref name="theringer-h2 retrospective" /><ref name="eurogamer-better than halo" /> Initially, ''Combat Evolved''{{'}}s multiplayer was supposed to involve larger maps and player counts than what shipped, and members of the team wanted to resurrect those plans for ''Halo 2''. The smaller multiplayer modes and local split-screen capabilities of the first game would have been removed. Designer [[Max Hoberman]] successfully argued against wholesale removal of a successful component from the previous game. He was put in charge of a small team to further develop the small-scale arena multiplayer, while the rest of the team developed a larger "Warfare" mode.<ref name="vice-untoldhistoryhalo" /> Bungie promised in previews that the core of this multiplayer would be squad-based online battles between human Spartans and Covenant Elites, with players able to call in airstrikes.<ref name="edge-no115" />{{rp|52}} Hoberman's pitch for ''Halo 2''{{'}}s arena multiplayer was to bring the fun of couch multiplayer online. As Hoberman was not an excellent video game player, he wanted to make sure the game remained fun for even lower-skilled players, rather than catering to the very competitive ones. The system of playlist matchmaking and allowing friends to "party up" to play games together were crucial to creating a global community of players.<ref name="theringer-h2 retrospective" /><!-- discussion of cut modes from Max Hoberman https://www.youtube.com/watch?v=E1a1FzQ3bdQ -->
The current known skulls are Thunderstorm, Blind, I Would Have Been Your Daddy, Catch, Grunt Birthday Party, Famine, Envy, Assassins, Mythic, Sputnik, Angry, Ghost, Iron, and Black Eye. These skulls are only available on the Legendary mode except the blind skull that's found on Outskirts. One skull shows no text when collected but examination of Halo 2 files shows this skull to be known internally as Whuppopotamous (fitting the acronym) and also Cowbell.
 
The story for ''Halo 2'' grew out of all the elements that were not seen in ''Combat Evolved''. Jason Jones organized his core ideas for the sequel's story and approached Staten for input. According to Staten, among the elements that did not make it to the finished game was a "horrible scene of betrayal" where Miranda Keyes straps a bomb to the Master Chief's back and throws him into a hole in revenge for her father's death; "Jason was going through a rather difficult breakup at the time and I think that had something to do with it," he said.<ref name="vice-untoldhistoryhalo" /><ref name="insidehalo2">{{Cite AV media |url=http://halo.bungie.org/misc/makingofhalo2mirrors.html |title=Bungie: Inside Halo 2 |date=September 2003 |publisher=Film Oasis |access-date=March 1, 2009 |archive-url=https://web.archive.org/web/20080928190919/http://halo.bungie.org/misc/makingofhalo2mirrors.html |archive-date=September 28, 2008 |url-status=live |format=mov |medium=Media DVD}}</ref> Staten and Griesemer discussed seeing the war from the Covenant perspective, forming the idea to have part of the game told from the perspective of a Covenant warrior known as the Dervish. Late in development, the Dervish became the Arbiter, after legal teams at Microsoft were afraid the game was sending a message about Islam.<ref name="vice-untoldhistoryhalo" /><ref name="dervish">{{Cite web |last=Kumar, Matthew |date=April 9, 2008 |title=Q&A: Englobe's Edwards Talks Gaming's 'Geocultural Risks' |url=http://www.gamasutra.com/php-bin/news_index.php?story=17985 |url-status=dead |archive-url=https://web.archive.org/web/20080412201559/http://www.gamasutra.com/php-bin/news_index.php?story=17985 |archive-date=April 12, 2008 |access-date=April 1, 2008 |website=[[Gamasutra]]}}</ref>
The Scarab's destructive main cannon is available as a handheld weapon. It is located in a hard-to-reach area in a level where the Scarab is present. To obtain the Scarab's powerful weapon you must first arrive at the end of a long bridge in the level Metropolis. After defeating all the enemies except one Banshee, the player must lure the Banshee into a tunnel and board it as it reaches the other side. After comandeering the Banshee, the player must fly to a certain grouping of buildings: the Scarab gun resides in the middle of a bridge connecting them. Although the Scarab gun uses the Plasma Rifle model, it shoots a huge blue plasma beam many times larger than the Master Chief. This trick is most easily performed in Co-op mode, where you have another player to provide backup and assistance.
 
In February 2003, Bungie began developing a gameplay demonstration for [[E3 (Electronic Entertainment Expo)|E3]] 2003. The demo, which was the first gameplay seen by the public, showcased new enemies and abilities. Many elements of the trailer, however, were not game-ready; the entire graphics engine used in the footage had to be discarded, and the trailer's environment never appeared in the final game due to limitations on how big the game environments could be.<ref name="vice-untoldhistoryhalo" /> Elements like vehicle hijacking were entirely scripted, and in order to keep performance at an acceptable level, a Bungie staff member deleted objects from the game as the player passed through. The restructuring of the engine meant that there was no playable build of ''Halo 2'' for nearly a year, and assets and environments produced by art and design teams could not be prototyped, bottlenecking development.<ref name="eurogamer-better than halo" /> Griesemer recalled that development was "moving backwards", and after E3 the team realized that much of what the team had worked on for the past two years would have to be scrapped.<ref name="vice-untoldhistoryhalo" />
===Glitches===
Players have discovered many glitches in Halo 2. For example, the player can leave the ordinary map boundaries by performing a "sword cancel," in which the player presses "Y", "R" twice, and then the "X" button on their gamepad, while having their rocket launcher out and their sword equipped, while facing another player. They will charge at the player but not slash them, allowing the sword user to fly over the other person and get over a boundary. Players could also use the "rocket glitch" to reach past the boundaries. However, this has been removed from the game with an update from Bungie. It works by having one player already in the position they wish to reach. While the player above is jumping, the player wanting to reach the position must have a rocket launcher, without ammunition, and a sword. While targeting the jumping man, from the bottom of the cross-hair, the player must switch between the rocket and sword to obtain access to the new area. The "rocket glitch" was disabled in the autoupdate, due to misuse in multiplayer battles. Two players can still use the "sword cancel" to gain access to new areas.
 
In order to ship the game, Bungie began paring back their ambitions for the single- and multiplayer parts of the game.<ref name="eurogamer-better than halo" /> All other Bungie projects, including ''Phoenix'', were cancelled, with their teams folded into ''Halo 2'' to complete the game. The campaign was completely rethought and remained unplayable for more than a year while the multiplayer was being developed. Ultimately, a third act of the game where Master Chief and Arbiter came together on Earth to defeat the Prophets was cut entirely. Staten hoped the resulting cliffhanger would be treated like the end of ''[[The Empire Strikes Back]]''.<ref name="vice-untoldhistoryhalo" /><ref name="ign-history">{{Cite web |last=McLaughlin, Rus |date=August 20, 2007 |title=IGN Presents The History of Halo |url=http://www.ign.com/articles/2010/09/10/ign-presents-the-history-of-halo?page=2 |url-status=live |archive-url=https://web.archive.org/web/20141127111945/http://www.ign.com/articles/2010/09/10/ign-presents-the-history-of-halo?page=2 |archive-date=November 27, 2014 |access-date=March 20, 2008 |website=IGN}}</ref> Planned vehicles, such as variants of the [[Warthog (Halo)|Warthog]] and an [[all terrain vehicle]], were scrapped.<ref name="edge-no115">{{Cite magazine |last=Staff |date=October 2002 |title=Prescreen Focus: Halo 2 |magazine=[[Edge (magazine)|Edge]] |publisher=Future plc |issue=115}}</ref>{{rp|49}}
Players have also discovered "super jumps", or bounces. Super jumps can be found on every map and are executed by crouching under something until your screen shakes and then jumping on a certain area, at which time the player will be propelled very high. Players have only discovered a few of these jumps and there are possibly many more, especially in the newer maps.
 
With the single-player mode in trouble, very little had been done with the large Warfare multiplayer mode. Eventually, the entire warfare mode was cut, and Hoberman's small team project became the shipping multiplayer suite.<ref name="vice-untoldhistoryhalo" /> Engineer Chris Butcher commented, "For ''Halo 2'' we had our sights set very high on networking. Going from having no internet multiplayer to developing a completely new online model was a big challenge to tackle all at once, and as a result we had to leave a lot of things undone in order to meet the ship date commitment that we made to our fans."<ref name="1up-does bungie hate halo 2">{{Cite web |last=Smith, Luke |author-link=Luke Smith (writer) |date=January 26, 2007 |title=Does Bungie Hate Halo 2? |url=http://www.1up.com/news/bungie-hates-halo2 |url-status=dead |archive-url=https://web.archive.org/web/20121019142721/http://www.1up.com/news/bungie-hates-halo2 |archive-date=October 19, 2012 |access-date=February 9, 2007 |website=[[1UP.com]]}}</ref>
One of these "super jumps", or bounces can be found in the map Zanzibar. This can be achieved by first going inside of the base. Where you find the battle rifle you would be able to see two windows with glass. Break these windows by either throwing a grenade or hitting them until no glass is left. If you look at the window to your nearest right, there would appear to be a glass shard in the wall. By walking left to the edge of the window and crouching, you should be able to get stuck into the wall. As this is happening, your screen should suddenly shake and at that time jump and if done correctly you should rise into the air and be on the top of the base. According to several non-US players, the superbounce can only be used on both Australian and American tv. However, it is much easier to perform on American tv.
 
As one of Microsoft's tentpole games, the publisher had two full-time user experience researchers managing a team of [[Game testing|game testers]] working on the title. The researchers used playtests, surveys, and [[usability testing]] to provide Bungie with input on how the game would be received. Feedback of the game's matchmaking system was very unfavorable, with the testers preferring the control offered by traditional servers. Researcher John Hopson recalled that while they suggested to Bungie they should change the matchmaking system, the developers remained steadfast their new approach would be better in the real world; Hopson later agreed with their choice, saying that his team had only narrowly avoided ruining the game.<ref name="polygon-ruining halo 2">{{Cite web |last=Hopson, John |date=July 2, 2019 |title=The time I tried to ruin Halo 2 |url=https://www.polygon.com/features/2019/7/2/18651880/the-time-i-tried-to-ruin-halo-2-user-research |access-date=March 9, 2021 |website=[[Polygon (website)|Polygon]] |publisher=Vox Media |archive-date=March 4, 2021 |archive-url=https://web.archive.org/web/20210304072740/https://www.polygon.com/features/2019/7/2/18651880/the-time-i-tried-to-ruin-halo-2-user-research |url-status=live }}</ref> To test real-world network conditions, Bungie ran a closed alpha of the multiplayer with 1000 Microsoft employees for five weeks.<ref name="gameinformer-no133">{{Cite magazine |last=Staff |date=May 2004 |title=Halo 2; Boot Camp |magazine=[[Game Informer]] |issue=133}}</ref>{{rp|4}}
These glitches have become a major problem in Halo 2's multiplayer over [[Xbox Live]]. For example, players can use the aformentioned "super jump" on the level Zanzibar to jump to the top of the level out of reach of most players. Since the release of the downloadable maps, Halo 2 hackers, users who edit the game with formerly illegally modified consoles (modifying Xbox consoles is now legal in the United States), began to [[mod (computer gaming)|mod]] the maps on the [[hard drive]]s of their Xbox's to receive advantages, such as weapons that do more damage, flying ground vehicles, etc. This has become such a widespread problem in the "Matchmaking" system that Bungie is constantly trying to resolve the problem by releasing autoupdates which ban hackers from the system and terminate their accounts. They have currently banned thousands of players and are working on cleaning up the rest.
 
Outside of Bungie, ''Combat Evolved''{{'}}s success had become a problem for ''Halo 2''{{'}}s development, as the success of the Xbox platform was riding on ''Halo''. Microsoft originally pressured Bungie to have the game ready as a launch title for Xbox Live in November 2002, which Bungie employees told them was impossible. At one point, Microsoft executives had a vote over whether to force Bungie to ship the incomplete game, or give them another year of development time. Microsoft Studios head [[Ed Fries]] walked out of the vote and threatened to resign to get Bungie the extra time.<ref name="vice-untoldhistoryhalo" />
==Plot synopsis==
{{spoiler}}
''Halo 2'' opens with an awards ceremony on the Cairo weapons platform orbiting Earth. This ceremony is cut short when a Covenant flagship jumps out of slipstream and sends boarding parties towards the platforms. These boarding parties are carrying heavy explosives designed to take out the MAC (Magnetic Accelerator Cannon) guns capable of destroying the Covenant flagships. Master Chief finds and disarms the bomb with the help of Cortana, then sends it to one of the Covenant ships and detonates it. They then head to Earth where the [[The Covenant|Covenant]] attack the city of [[New Mombasa]], repelled with the assistance of the [[Master Chief (Halo)|Master Chief]]. It continues across another ring world, dubbed "[[Delta Halo]]", as the crew of the UNSC vessel ''In Amber Clad'' attempt to discover the reason for the Covenant's incursion. There, the Master Chief kills one of the Covenant's three [[High Prophets (Halo)|High Prophet]] leaders, which ultimately triggers a [[civil war]] inside the Covenant. Meanwhile, the fleet commander who led the Covenant forces in ''[[Halo: Combat Evolved|Halo]]'' is stripped of his rank, only to assume the role of the [[Arbiter (Halo)|Arbiter]], the greatest of the Covenant warriors. His first mission, to silence a heretic who doubts the Prophets' teachings, starts him on a path which will make him question his beliefs.

The Master Chief and the Arbiter meet upon the release of the [[The Flood (Halo)|Flood]] and the discovery of the Prophets' true objective: driven by their ancient religion, they seek to activate Delta Halo, which would cause the death of every sentient being in the galaxy. A mysterious Flood creature called the [[Gravemind]] sends the Arbiter and Master Chief in separate directions to prevent The High Prophets from activating Delta Halo.
 
===Audio===
The Master Chief finds himself upon the nearby Covenant Holy City, [[High Charity]], a gargantuan space station, and pursues the remaining Prophets. After capturing the ''In Amber Clad'', the Flood, led by the Gravemind, arrive on the city and begin to try and capture it. The only remaining High Prophet, Truth, escapes on a [[Forerunners|Forerunner]] vessel. The Master Chief stows away on board, but [[Cortana (Halo)|Cortana]] stays behind because if all else fails, she would detonate the ''In Amber Clad'''s engine reactors. This will destroy Delta Halo and High Charity, stopping [[Tartarus (Halo)|Tartarus]] from activating it, while preventing the Flood's escape across the galaxy. However, at the end, Cortana not only fails to destroy High Charity, but she also chooses to answer the questions of Gravemind.

''Halo 2''{{'}}s soundtrack was composed primarily by [[Martin O'Donnell]] and his musical partner [[Michael Salvatori]], the team that had composed the critically acclaimed music of ''Halo''.

In the summer of 2004, producer [[Nile Rodgers]] and O'Donnell decided to release the music from ''Halo 2'' on two separate [[Compact Disc|CDs]]; the first (Volume One) would contain all the themes present in the game as well as music "inspired" by the game; the second would contain the rest of the music from the game, much of which was incomplete, as the first CD was shipped before the game was released.<ref>{{Cite AV media notes |author-link=Martin O'Donnell |author=O'Donnell, Martin |year=2006 |title=Halo 2 Original Soundtrack: Volume Two |publisher=[[Sumthing Distribution]]}}</ref> The first CD was released on November 9, 2004, and featured guitar backing by [[Steve Vai]].

Uniting the separatist faction of the Covenant on Delta Halo, and with the help of [[Halo characters#Avery Johnson|Sergeant Johnson]], the Arbiter succeeds in preventing Tartarus from activating the installation. However, the Halo and its counterparts across the galaxy are left on standby alert, awaiting a trigger signal from "[[The Ark (Halo)|The Ark]]", whose ___location is yet unknown, but is believed to be on Earth. Meanwhile, the Forerunner vessel arrives near Earth, with the Master Chief on board. The game ends with a [[cliffhanger]], with the last cutscene showing the Master Chief about to enter the battle to save Earth while Cortana meets Gravemind on High Charity for unknown reasons. The stage is set for the final battles of the Human-Covenant and Covenant civil wars in ''Halo 3'' or Bungie's next project (has yet to be announced).

''Halo 2'' was officially announced in September 2002 with a cinematic trailer,<ref name="eurogamer-better than halo" /> scheduled for a Holiday 2003 release. The first major look at the game came with the E3 2003 demo in May; ''Halo 2'' was Microsoft's strongest showing at the event, and some journalists believed the game looked too good to be live gameplay and must have been a scripted cutscene.<ref name="ign-coveringhalo2">{{Cite web |last=Goldstein |first=Hilary |date=September 9, 2004 |title=Covering Halo 2: An Editor's Journey |url=https://www.ign.com/articles/2004/09/10/covering-halo-2-an-editors-journey |access-date=January 14, 2021 |website=[[IGN]] |publisher=Ziff Davis |archive-date=January 16, 2021 |archive-url=https://web.archive.org/web/20210116120525/https://www.ign.com/articles/2004/09/10/covering-halo-2-an-editors-journey |url-status=live }}</ref> After delays, the game was shifted to a first-quarter 2004 release, then to Holiday 2004.<ref name="ign-2004 date">{{Cite web |last=Boulding |first=Aaron |date=March 7, 2003 |title=Halo 2 in '04 |url=https://www.ign.com/articles/2003/03/07/halo-2-in-04 |access-date=March 9, 2021 |website=[[IGN]] |publisher=Ziff Davis |archive-date=March 27, 2023 |archive-url=https://web.archive.org/web/20230327070654/https://www.ign.com/articles/2003/03/07/halo-2-in-04 |url-status=live }}</ref><ref name="ion-fall 2004 date">{{Cite web |last=Staff |date=January 30, 2004 |title=Halo 2 Date |url=https://www.ign.com/articles/2004/01/30/halo-2-date |access-date=March 8, 2021 |website=[[IGN]] |publisher=Ziff Davis |archive-date=April 3, 2022 |archive-url=https://web.archive.org/web/20220403213615/https://www.ign.com/articles/2004/01/30/halo-2-date |url-status=live }}</ref> The final November 9 release date was confirmed at E3 2004, where the game's multiplayer was playable on the show floor.<ref name="ign-e32004postmortem">{{Cite web |last=Perry |first=Douglass |date=June 9, 2004 |title=E3 Post Mortem, Part I |url=http://www.ign.com/articles/2004/06/10/e3-post-mortem-part-i |access-date=March 9, 2021 |website=[[IGN]] |publisher=Ziff Davis |archive-date=March 27, 2023 |archive-url=https://web.archive.org/web/20230327070654/https://www.ign.com/articles/2004/06/10/e3-post-mortem-part-i |url-status=live }}</ref> Microsoft executive [[Peter Moore (businessman)|Peter Moore]] rolled up his sleeve to reveal the date tattooed on his bicep.<ref name="venturebeat-peter moore bye">{{Cite web |last=Takahashi |first=Dean |date=April 14, 2017 |title=EA's Peter Moore says a fond adios to the game industry |url=https://venturebeat.com/2017/04/14/eas-peter-moore-says-a-fond-adios-to-the-game-industry/ |access-date=March 9, 2021 |website=[[VentureBeat]] |archive-date=May 1, 2022 |archive-url=https://web.archive.org/web/20220501083944/https://venturebeat.com/2017/04/14/eas-peter-moore-says-a-fond-adios-to-the-game-industry/ |url-status=live }}</ref><ref>{{Cite web |last=Perry |first=Douglass |date=October 11, 2004 |title=Halo 2 is Golden |url=https://www.ign.com/articles/2004/10/11/halo-2-is-golden |access-date=March 9, 2021 |website=[[IGN]] |publisher=Ziff Davis |archive-date=May 1, 2022 |archive-url=https://web.archive.org/web/20220501084124/https://www.ign.com/articles/2004/10/11/halo-2-is-golden |url-status=live }}</ref>

Microsoft intended to market ''Halo 2'' not just as a video game, but as a cultural event. Part of its widespread appeal would come from the social nature of the game's multiplayer, but Microsoft also heavily promoted and marketed the game. A trailer for the game was shown in movie theaters, making ''Halo 2'' the first video game so advertised.<ref name="theringer-h2 retrospective">{{Cite web |last=Agnello, Anthony |date=November 11, 2019 |title=When 'Halo 2' Invaded Planet Earth |url=https://www.theringer.com/2019/11/11/20958715/halo-2-anniversary-first-person-shooter-xbox-master-chief-history-i-love-bees |access-date=January 24, 2020 |website=[[The Ringer (website)|The Ringer]] |archive-date=December 18, 2019 |archive-url=https://web.archive.org/web/20191218065943/https://www.theringer.com/2019/11/11/20958715/halo-2-anniversary-first-person-shooter-xbox-master-chief-history-i-love-bees |url-status=live }}</ref> Hype for the title was fueled by the press, with Microsoft telling one journalist that their ''Halo 2'' review would be the most consequential of their career.<ref name="ign-halo2_epilogue">{{Cite web |last=Perry |first=Douglass |date=December 7, 2004 |title=Epilogue: Halo 2 |url=https://www.ign.com/articles/2004/12/08/epilogue-halo-2 |access-date=January 14, 2021 |website=[[IGN]] |publisher=Ziff Davis |archive-date=January 15, 2021 |archive-url=https://web.archive.org/web/20210115225502/https://www.ign.com/articles/2004/12/08/epilogue-halo-2 |url-status=live }}</ref> The marketing heavily focused on Master Chief and the defense of earth, leaving the reveal of the Arbiter as a playable character a surprise.<ref name="denofgeek-halo2history">{{Cite web |last=Gallagher |first=Jason |date=November 14, 2014 |title=Halo 2: The History of a Controversial FPS Classic |url=https://www.denofgeek.com/games/halo-2-the-history-of-a-controversial-fps-classic/ |access-date=March 16, 2021 |website=[[Den of Geek]] |archive-date=October 18, 2020 |archive-url=https://web.archive.org/web/20201018191618/https://www.denofgeek.com/games/halo-2-the-history-of-a-controversial-fps-classic/ |url-status=live }}</ref>
==Music==
The ''Halo 2'' soundtrack was mostly composed by [[Martin O'Donnell]], who had also composed the music of ''Halo''. [[Steve Vai]] provided guitar backing for many tracks. Additional tracks were also provided by various outside musicians, such as Joe Satriani (for the remixed theme song, which includes new guitar solos).
 
''Halo 2''{{'}}s release was preceded with promotions and product tie-ins. There was a ''Halo 2'' Celebrity Pre-Release Party at E3 2004, in which a private home was transformed to replicate the world of ''Halo'', complete with camouflaged Marines and roaming Cortanas.<ref>{{Cite web |date=October 27, 2004 |title=Hollywood's Hooked On ''Halo'' |url=http://www.xbox.com/en-US/community/personality/guests/20041027-stars.htm |archive-url=https://web.archive.org/web/20070219010712/http://www.xbox.com/en-US/community/personality/guests/20041027-stars.htm |archive-date=February 19, 2007 |access-date=December 26, 2006 |website=Xbox.com |publisher=Microsoft}}</ref> Launch events were held worldwide, with players waiting for hours in a line that stretched two blocks in [[Times Square]], [[New York City]].<ref name="ign-timessquare_launch">{{Cite web |last=Brudvig |first=Erik |date=November 12, 2004 |title=Master Chief Lands in New York |url=https://www.ign.com/articles/2004/11/12/master-chief-lands-in-new-york |access-date=January 14, 2021 |website=[[IGN]] |publisher=Ziff Davis |archive-date=January 16, 2021 |archive-url=https://web.archive.org/web/20210116092142/https://www.ign.com/articles/2004/11/12/master-chief-lands-in-new-york |url-status=live }}</ref> The French version of the game [[Copyright infringement of software|leak]]ed on the internet in October, and circulated widely.<ref>{{Cite magazine |date=January 2005 |title=Stolen!

'''The Last Spartan''', is the signature theme tune for Halo 2.
The bands [[Incubus]], [[Breaking Benjamin]], and [[Hoobastank]] also feature on the official soundtrack and to a certain extent, in the game. The song [[Blow Me Away]] is considered the most popular of these contributions.
 
In addition to more traditional forms of promotion, ''Halo 2'' was also part of an elaborate [[Alternate Reality Game]] project titled ''[[I Love Bees]]''. Microsoft approached 42 Entertainment's Elan Lee, who had helped launch the Xbox with Microsoft, on producing a tie-in game.<ref name="theringer-h2 retrospective" /> ''I Love Bees'' cost an estimated one million dollars. The game centered on a hacked [[website]], supposedly a site about [[beekeeping]], where an AI from the future was residing.<!-- another sentence about what players did--> The project garnered significant attention, drawing attention away from the ongoing [[2004 United States presidential election|2004 U.S. Presidential Election]].<ref>{{Cite web |last=Iker, Simone |date=July 23, 2004 |title=Halo 2 Trailer, ILB, Halo Done Quick |url=http://games.slashdot.org/story/04/07/23/1912259/Halo-2-Trailer-Gets-Subliminal-Halo-Done-Quick |url-status=live |archive-url=https://web.archive.org/web/20110612023017/http://games.slashdot.org/story/04/07/23/1912259/Halo-2-Trailer-Gets-Subliminal-Halo-Done-Quick |archive-date=June 12, 2011 |access-date=March 29, 2007 |publisher=[[Slashdot]]}}</ref><ref>{{Cite magazine |last=Terdiman, Daniel |author-link=Daniel Terdiman |date=October 18, 2004 |title=I Love Bees Game a Surprise Hit |url=https://www.wired.com/culture/lifestyle/news/2004/10/65365 |url-status=dead |magazine=[[Wired (magazine)|Wired]] |archive-url=https://web.archive.org/web/20110710053650/http://www.wired.com/culture/lifestyle/news/2004/10/65365 |archive-date=July 10, 2011 |access-date=March 29, 2007}}</ref> The game won an award for creativity at the 5th annual [[Game Developers Choice Awards]]<ref>{{Cite web |date=March 10, 2005 |title=5th Annual Game Developers Choice Awards |url=http://www.gamechoiceawards.com/archive/gdca_5th.htm |archive-url=https://web.archive.org/web/20060326025405/http://www.gamechoiceawards.com/archive/gdca_5th.htm |archive-date=March 26, 2006 |access-date=March 29, 2007 |publisher=[[Game Developers Choice Awards]]}}</ref> and was nominated for a [[Webby Award|Webby]] award.<ref>{{Cite web |last=Peters, Steve |date=April 12, 2005 |title=I Love Bees Nominated for Webby Award |work=ARGNet: Alternate Reality Gaming Network &#124; Your first choice for ARG news. |url=http://www.argn.com/2005/04/i_love_bees_nominated_for_webby_award/ |url-status=live |archive-url=https://web.archive.org/web/20090619071811/http://www.argn.com/2005/04/i_love_bees_nominated_for_webby_award/ |archive-date=June 19, 2009 |access-date=March 29, 2007 |publisher=ARGN}}</ref> Ultimately, nearly 3 million people participated in the game.<ref name="theringer-h2 retrospective" />

A common complaint regarding ''Halo 2's'' online play has been the widespread cheating which occurred almost immediately upon the game's release. Users exploited bugs in the game and vulnerabilities of the network to win ranked games and thus increase their matchmaking rank. In response to these complaints, Bungie released an automatic update for ''Halo 2'' (a mandatory patch) on Monday, April 18th, 2005, which fixed many of the various bugs and cheats in the game (though some inevitably persist), slimmed down split-screen HUD information, and rebalanced various weapons to promote use of single-wield weapons, grenades, and melee attacks. For example, the melee attacks and grenades are now far more powerful. Melee attacks have also been given a lunge ability like that of the Energy Sword, though with a much shorter range. A full list of changes can be seen [http://www.bungie.net/News/TopStory.aspx?story=weeklywhatsapril15th&p=3014696 here]. This brings ''Halo 2'' up to Version 1.1.
 
The game sold 2.4 million copies and earned up to [[United States Dollar|US$]]125 million in its first 24 hours on store shelves, outgrossing the film ''[[Pirates of the Caribbean: Dead Man's Chest]]'' as the highest-grossing release in entertainment history.<ref name="cbc-birth of a nation halo 2">{{Cite web |last=Bolton, Greg |date=January 14, 2005 |title=Birth of a Nation; The genius marketing campaign behind Halo 2 |url=http://www.cbc.ca/arts/media/halo.html |url-status=dead |archive-url=https://web.archive.org/web/20101017062000/http://www.cbc.ca/arts/media/halo.html |archive-date=October 17, 2010 |website=[[CBC.ca]] |publisher=Canadian Broadcasting Corporation}}</ref><ref>{{Cite web |last=Thorsen, Tor |date=November 10, 2004 |title=Microsoft raises estimated first-day Halo 2 sales to $125 million-plus |url=http://www.gamespot.com/news/microsoft-raises-estimated-first-day-halo-2-sales-to-125-million-plus-6112915? |url-status=dead |archive-url=https://web.archive.org/web/20120203033402/http://www.gamespot.com/news/microsoft-raises-estimated-first-day-halo-2-sales-to-125-million-plus-6112915 |archive-date=February 3, 2012 |access-date=March 15, 2006 |website=[[GameSpot]]}}</ref> The game sold 260,000 units in the [[United Kingdom]] in its first week, making it the third fastest-selling title in that territory.<ref name=best-selling/> It ultimately received a "Double Platinum" sales award from the [[Entertainment and Leisure Software Publishers Association]] (ELSPA),<ref name="dpelspa">{{Cite web |title=ELSPA Sales Awards: Double Platinum |url=http://www.elspa.com:80/?i=3945 |url-status=dead |archive-url=https://web.archive.org/web/20090520070249/http://www.elspa.com/?i=3945 |archive-date=May 20, 2009 |website=[[Entertainment and Leisure Software Publishers Association]]}}</ref> indicating sales of at least 600,000 copies in the United Kingdom.<ref name="gamasutrasales">{{Cite web |last=Caoili, Eric |date=November 26, 2008 |title=ELSPA: ''Wii Fit'', ''Mario Kart'' Reach Diamond Status In UK |url=https://www.gamasutra.com/view/news/112220/ELSPA_Wii_Fit_Mario_Kart_Reach_Diamond_Status_In_UK.php |url-status=dead |archive-url=https://web.archive.org/web/20170918063107/https://www.gamasutra.com/view/news/112220/ELSPA_Wii_Fit_Mario_Kart_Reach_Diamond_Status_In_UK.php |archive-date=September 18, 2017 |website=[[Gamasutra]]}}</ref> In the United States, it was the second best-selling [[2004 in video games|game of 2004]] (after ''[[Grand Theft Auto: San Andreas]]'') with sales of {{nowrap|4.2 million}} that year,<ref>{{Cite book |last1=Bellavista |first1=Paolo |url=https://books.google.com/books?id=d0ErBgAAQBAJ&pg=PA1200 |title=The Handbook of Mobile Middleware |last2=Corradi |first2=Antonio |date=April 19, 2016 |publisher=[[CRC Press]] |isbn=978-1-4200-1315-3 |page=1200 |access-date=February 14, 2021 |archive-date=March 27, 2023 |archive-url=https://web.archive.org/web/20230327070654/https://books.google.com/books?id=d0ErBgAAQBAJ&pg=PA1200 |url-status=live }}</ref><ref>{{Cite news |date=January 18, 2005 |title=NPD: $9.9 billion worth of console games sold in 2004 |work=[[GameSpot]] |url=https://www.gamespot.com/articles/npd-99-billion-worth-of-console-games-sold-in-2004/1100-6116499/ |access-date=February 13, 2021 |archive-date=February 24, 2009 |archive-url=https://web.archive.org/web/20090224041447/http://www.gamespot.com/news/6116499.html |url-status=live }}</ref><ref>{{Cite news |last=Lee |first=Garnett |title=Videogame Sales Total $9.9 Billion in 2004 |work=[[1UP.com]] |url=http://www.1up.com/do/newsStory?cId=3137806 |url-status=dead |access-date=February 10, 2021 |archive-url=https://web.archive.org/web/20050210043723/http://www.1up.com/do/newsStory?cId=3137806 |archive-date=February 10, 2005}}</ref> and the eighteenth best-selling game of the [[2000s]] decade.<ref>{{cite web|author=Grubb, Jeff|date=January 16, 2020|url=https://venturebeat.com/business/the-top-20-best-selling-games-of-the-decade-in-the-u-s/|title=NPD: The top 20 best-selling games of the decade in the U.S.|website=[[VentureBeat]]|access-date=November 29, 2024}}</ref>
''Halo 2'' also supports downloadable content, with Bungie making various new multiplayer maps available. Four maps were made available to download on Monday, April 25th, 2005. Two of these were immediately free to download (the "Bonus Pack"), while the other two (the "Killtacular Pack") had a charge attached (US$5.99, £2.99) until July the 5th (in actuality, late June), when they too became free to download.

Another update was added in July, 2005 (a week or so after the release of the map pack). The update added a detection tool that would automatically detect and ban 'modders' using modified content on their Xboxes. Modified versions of the downloadable maps would allow people to use cheats such as 'super jump' and 'automatic reload' during matches on Xbox Live. Any players who are detected using modified content would be automatically banned from Matchmaking on Xbox Live. The update also fixes a teleporter glitch on the map, Relic.

''[[Edge (magazine)|Edge]]''<nowiki>'</nowiki>s review concluded that ''Halo 2'' could be summed up with a line from its script: "It's not a new plan.

<!-- campaign -->
While ''Halo 2'' has won many awards and raked in colossal profits, debate has risen over the merits of such success, especially when faced with comparisons to the immense impact on the console market that the first ''Halo'' had. Many gamers even credit ''Halo CE'' with singlehandedly propping up the Microsoft Xbox's image and sales through its first generation of games. In this light, it's easy to see how some could be disgruntled &ndash; even an excellent sequel would have trouble standing up to the original.
The game's campaign mode received some criticism for being too short,<ref>{{Cite news |last=Ham, Tom |date=November 14, 2004 |title=Reviews: Halo 2 and Donkey Konga |url=https://www.washingtonpost.com/wp-dyn/articles/A47150-2004Nov13.html |url-status=live |archive-url=https://web.archive.org/web/20070807221813/http://www.washingtonpost.com/wp-dyn/articles/A47150-2004Nov13.html |archive-date=August 7, 2007 |access-date=March 20, 2007 |newspaper=[[The Washington Post]]}}</ref> and for featuring an abrupt [[cliffhanger]] ending.<ref name="gamespot-review">{{Cite web |last=Kasavin, Greg |date=November 4, 2007 |title=''Halo 2'' for Xbox Review |url=http://www.gamespot.com/halo-2/reviews/halo-2-review-6112628/ |url-status=dead |archive-url=https://web.archive.org/web/20111225103937/http://www.gamespot.com/halo-2/reviews/halo-2-review-6112628 |archive-date=December 25, 2011 |access-date=February 10, 2007 |website=[[GameSpot]]}}</ref> ''GameSpot'' noted that although the story's switching between the Covenant and human factions made the plot more intricate, it distracted the player from Earth's survival and the main point of the game;<ref name="gamespot-review" /> while ''Edge'' labeled the plot "a confusing mess of fan-fiction sci-fi and bemusing ''[[Star Wars: Episode II – Attack of the Clones|Episode-II]]''-style politics."<ref name=edgereview /><ref name="ign-halo2_epilogue" />

''Halo 2''{{'}}s multiplayer suffered from widespread [[cheating]] on release. Some players used "standbying" or "lag killing" to cheat, where the player hosting the game intentionally pressed the standby button on his or her modem.

Some players dispute whether ''Halo 2'' is a good game at all. A large chunk of this group consists of disgruntled ''Halo'' fans who feel that certain changes have made the game unbalanced, mainly in multiplayer gameplay.
Several argumentative complaints registered by members of this movement:
 
''Halo 2'' was one of the Xbox games that was [[backwards compatibility|backwards-compatible]] on the Xbox 360. On the newer console, the game runs at high-definition [[720p]] with scene-wide [[anti-aliasing]].<ref name="bungie.net-anniversary">{{Cite web |last=O'Connor, Frank |date=November 9, 2005 |title=Halo 2: One Year Later |url=http://halo.bungie.net/news/content.aspx?type=topnews&cid=7139 |url-status=dead |archive-url=https://archive.today/20130717133508/http://halo.bungie.net/news/content.aspx?type=topnews&cid=7139 |archive-date=July 17, 2013 |access-date=December 3, 2007 |publisher=[[Bungie]]}}</ref> The ability to download DLC for ''Halo 2'' was discontinued when support for original Xbox Live games was terminated in 2010.<ref>{{Cite web |last=Peckham |first=Matt |date=April 15, 2010 |title=So Long and Thanks for Halo 2, Xbox LIVE |url=http://www.pcworld.com/article/194323/so_long_and_thanks_for_halo_2_xbox_live.html/ |url-status=dead |access-date=May 4, 2021 |website=[[PC World]] |archive-date=October 30, 2010 |archive-url=https://web.archive.org/web/20101030003110/http://www.pcworld.com/article/194323/so_long_and_thanks_for_halo_2_xbox_live.html }}</ref>
*The lack of mid-to-long range weapons in the game.
 
===Ports and rereleases===
*The Sub-machine gun starting weapon which some claimed was imbalanced and underpowered, leaving the outcome of the game determined by a combination of luck and who can get to more dominating weapons first.

*Toned down pistol. In ''Halo'', the [[List of weapons in Halo: Combat Evolved|M6D pistol]] was an extremely powerful sidearm that, if aimed precisely, killed any shielded enemy with three shots to the head. This made it one of the best multiplayer weapons and the main weapon used by many experienced ''Halo'' players. In ''Halo 2'', however, the pistol appears to be a support weapon of dubious functionality, and has lost a considerable amount of power.

===Matchmaking===
{{Authority control}}
 
{{DEFAULTSORT:Halo 2}}
A number of players take issue with Xbox Live Matchmaking. One frequent complaint involves the default [[List of weapons in Halo 2|weapon]] settings used in [[multiplayer gametypes]], situations where the player starts off with the relatively underpowered and inaccurate SubMachine Gun. These players feel that a starting weapon such as the Battle Rifle would make much more sense in the competitive environment of matchmaking, allowing for a greater emphasis on aim and [[strafing]] techniques. Others feel that the Battle Rifle is an annoying weapon and isn't nearly as much as "fun" as the traditional SMG. Bungie has since responded to these demands by including the Battle Rifle as a default weapon in several playlist scenarios. Since players can not choose to skip these scenarios, players are forced to quit and try again for an actual "fun" Halo 2 multiplayer game.

Many members of the [[Major League Gaming]] league share similar gripes. Fans of the strict policies and gametypes endorsed by MLG routinely posted on the Bungie.net forums arguing for these to be included in matchmaking, often proposing the compromise of an MLG-style playlist. These complaints escalated until Bungie.net moderators eventually banned all talk of MLG related proposals. Now Bungie has added Team Hardcore playlist to enact several of the key MLG ideas into matchmaking.

Conflicts also arose because of Bungie's ''Halo 2'' [[game engine]]. This engine used an on the fly rendering in an attempt to create a game without load times. The downside was that the textures were rendered a second or two after the level loaded. Nearly all of this happens in the [[cutscenes]] used to separate levels and level segments. A few wish that such implementation was optional and would rather sit through loadscreens in exchange for presentational consistency.

===Offline Multiplayer===
 
Another area that is criticised is the lack of computer controlled enemies -or bots- in multiplayer. While Halo 2's main attraction was it's online multiplayer component, it's failure to improve over the original Halo in regards to players who do not have Xbox Live is sometimes pointed out as being negligent. The omission of bots is also strange in that the AI in the singleplayer section of the game is fairly intelligent and dynamic, and could have been transferred to multiplayer with a reasonable amount of ease. However, early rumours in Halo 2's development as to the inclusion of bots were firmly rebutted by Bungie.
 
Many online players of Halo 2 suggest that bots would be a waste of development time for the game, although for the offline community it is another example of them being overlooked in favour of online multiplayer. Halo 2 certainly shines in this area, but for a game aiming to push the limits of the console FPS, the absence of bots is fairly odd, given that they are present in earlier console games such as [[Timesplitters 2]], XIII, [[Perfect Dark]], and even [[The World Is Not Enough]].
 
===Story===
 
Other disputes concern the creative liberties taken with the story. Several fans felt that the game's plot was too different from what the previews suggested. They felt that the struggle to defend Earth should have been the centerpiece of the story rather than a preface to the reiteration of the first game's storyline. This was most likely due to Bungie's policy against the divulsion of [[Spoiler (media)|spoilers]] prior to the game's release, a move reflected in ''Halo's'' advertising.
 
More controversy was generated by the game's abrupt [[cliffhanger]] ending. Many players (and some reviewers [http://www.gamespot.com/xbox/action/halo2/review-2.html]) were dissatisfied with the apparent lack of climax and some claimed that Microsoft forced Bungie to cut the last level. However, according to the Collector's Edition supplemental DVD, Bungie's decision to resort to a [[cliffhanger]] ending was necessitated by "time constraints". After being given almost three years to finish the project, with numerous and competent staff, this was seen as a rather dubious excuse, and the outcome was less than satisfactory for many.
 
Players also lamented the demystification of the Covenant enemies. In ''Halo 2'' Bungie decided to further humanize the alien enemies; aliens suddenly spoke English, due to the Master Chief's "Covenant translator" built into his new armor (the Covenant actually spoke backwards English in the original ''Halo''.. Also included were cutscenes that shed light on their socialization, inevitably compromising the Covenant's menacing appearance. Further, the decision to include a playable Covenant character (The Arbiter) proved a risky move that was not universally supported. Jokingly referred to as an example of the ''[[Metal Gear Solid 2]]'' syndrome, it shifted focus away from the franchise's main character (Master Chief).
